CORN-HUSKING AND FODDER-SHREDDING MACHINE.

SPECIFICATION forming part of Iietters Patent No. 738,776, dated September 15, 1903.

l Application filed May 8, 1902. Serial No. 106,476. (No model.)

To all whom it may concern:

Be it known that we, SIMON, S. OREIDER and ISAAOKORN, citizens of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented a new and useful Corn-Husking and Fodder-Shred ding Machine, of which the following is a specification.

. Our invention is an improved corn-husk mg and fodder-shredding machine; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed. v

, In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of a corn-husking and fodder-shredding machine embodying our improvements. Fig.2 is a top plan View of the same, partly in section,

on a plane indicated by the line a a of Fig. 1. Fig. 3' is a detail transverse sectional view taken on a plane indicated by the line Z2 b of Fig. 2. Fig. 4 is a detail perspective view of a pair of the shredding-disks. Fig. 5 is a similar view showing a modified form of the shredding-disk. Fig. 6 is a diagrammatic top plan view showing several arrangements of the shredding-rollers with reference to the snapping-rolls. g

In the embodiment of our invention we employ a pair of snappingrolls 1, each of which comprises a plurality of circular disks 2, spaced apart bycollar-disks 3, which are of less diameter than the disks 2. The latter are provided with peripheral teeth 4, which extend transversely thereof and are triangular in cross-section. The collar-disks have similar peripheral teeth 5, which are smaller than. the teeth 4 of the disks 2, and owing to the difference in sizebetween the disks and the collar-disks the teeth of the latter are disposed within the radius of the teeth on the disks 2. The larger disks 2 of the respective snapping-rolls are intercurrentthat is to say, the disks 2 of each snapping-roll are disposed opposite the smaller collar-disks of the opposing roll-and the peripheries of the said tween the respective peripheries of the disks and collar-disks which admit of the passage of cornstalks moving endwise with respect to their own lengths and transversely with respect to the snapping-rolls, so that the cornstalks as they pass between the snappingrolls will be disintegrated and broken, as will be understood. In addition to their function in disintegrating and breaking the cornstalks the snapping-rolls act efliciently as such to snap the ears of corn from the stalks as the latter pass between the snapping-rolls.

The snapping rolls are here shown as mounted transversely in a frame 6. The latter may be either of the form here shown or of any other suitable construction, and within the scope of our invention the snapping-rolls may be rotated by any suitable means. They are here shown as provided at one end of their respective shafts with intermeshed spurgears 7, which cause the said snapping-rolls to rotate in opposite directions. A pulley 8 is shown on the shaft of one of the snappingrolls, and the said pulley is connected by an endless belt 9 to a pulley 10 on one end of a shaft 11, which shaft is j ournaled in bearings at the feed end of the frame and'is provided with a plurality of eccentrics 12. The latter project in different directions from the shaft 11. As here shown, alternately-disposed cccentrics project in opposite directions from the shaft; but we do not limit ourselvesin this particular. The eccentric-straps 13 on the eccentrics 12 are connected by pitmen 14 to longitudinally-movable feed-bars 15. The latter are here shown as having their outer ends disposed to move in guides 16 and are supported near their inner ends by oscillating links 17, which are shown as pivotally connected thereto and to a transversely-disposed supporting-bar 18. The upper sides of the feed-bars are provided with feed-teeth 19. The feed-bars 15 are substantially of the same construction as the feed-bars shown and de* scribed in the patent granted to Isaac Korn and S. S. Oreider September 13, 1828, No. 610,713, and the same serve to feedbundles of corn endwise to the snapping-rolls, as will be understood The feed-bars form thebottom of a feed-trough the sides of which are formed by the casing at the sides of theframe 6, as shown at 20 in Figs. 1 and 2.

The inner ends of the reciprocating feed ICO bars 15 are at some distance from the snapping-rolls, and in order to prevent the space between the inner ends of the feed-bars and the snapping-rolls from becoming choked we provide throatfeed plates 21, which are preferably of the construction shown in Figs. 1 and 2, and are su fficiently wide to almost completely bridge the space between-the sides of the frame and immediately in front of the snapping-rolls. The feed-bars, which are considerabl y narrower, are spaced apart, as shown in Fig. 2. The throat feed-plates, by being secured to the inner ends of the feed-bars, are moved back and forth by the latter and serve to prevent an accumulation of material in advance of the snapping-rolls, and are particularly useful in feeding the latter with loose or tangled material. It will be understood that as the stalks of corn pass between the snapping-rolls the ears are snapped therefrom by the action of the snapping-rolls and fall directly therefrom onto the longitudinallyd'nclined husking-rolls 22, which are shown in Fig. 1. preferably of the construction shown and described in Letters Patent of the United States No. 618,249, granted to us November 1, 1898,

and need not, therefore, be more fully de-- scribed in this specification.

At the rear ends of the husking-rolls and in line'therewith are shredding-rolls 23. The same are formed of a 'plurality of intercurrent-disks spaced apart by collar-disks and of the same construction and relative arrangement as the disks or collar-disks which form the snapping-rolls, hereinbefore described.

It will be observed by reference to Figs. 1'

and 2 that the shredding-rolls 23 are disposed at right angles to the snapping-rolls 1 and with their lower ends below the snappingrolls.

the shredder-rolls and substantially parallel with the latter in such position that the fodder is caught by the teeth of the disks of the shredder-rolls and drawn downwardly between the same and subjected to the shearing action of the overlapping toothed edges of thedisks of the shredding-rolls, and thereby cut into lengths equal to the width or thickness of the said disks. Owing to the fact that the fodder passes between the snap- 3 ping-rolls atsubstantially right angles to their axes, the fodder, although crushed,

These husking-rolls are Hence the cornstalks which pass be-- tween the snapping-rolls are delivered onto The bands of twine, how

and to regulate the feed thereof to the shredding and cutting rolls, we provide a regulating-gate 24:, which is hung above the shredding and cutting rolls and transversely in the frame l,under a cover 25, which extends from above the snapping-rolls to the rear end of the frame, and the said regulating-gate is hinged at its upper side, as at 26. The same normally is disposed by gravity in the position shown in Fig. 1. As the fodder passes under the gate 24 the latter swings rearwardly on its hinge; but owing to its weight the regulating-gate prevents the corn-fodder from being fed in masses from the snappingrolls to the shredding-rolls.

Any suitable number of the shredding-rolls may be used. We here show two pairs of them in Fig. 2. \Vithin the scope of our invention any appropriate means may be employed for driving the shredding andcutting rolls. For the purposes of this specification the rolls of the respective pairs are shown connected together by intergeared spurwheels 27, and the shaft of one of each pair of shredding and cutting rolls is shown connected to a power-shaft 28 by miter-gears 29. We also show this power-shaft connected to the shaft of one of the snapping-rolls by pulleys 30 31 and an endless belt 32.

Pairs of shredding and cutting rolls are shown as separated by a crest or divider-bar 33. WVe also provide a throat-guide 34, which is preferably of the form shown in Figs. 1, 2,

' and 3, covers the snapping-rolls, extends rear- Wardly therefrom over the lower portions of the inclined cutting and shredding rolls, and

serves to feed the fodder from the snappingrolls to the cutting and shredding rolls.

It will be observed by reference to Fig. 1'

of the drawings that the shredding andc utting rolls are inclined and extend upwardly beyond the snapping-rolls. This causes the fodder to be so disposed longitudinally of'the shredding and cutting rolls as to facilitate the action of the shredding and cutting disks in grasping the fodder and drawing it between the pairs of shredding and cutting rolls, so that each stalk becomes cut in a number of short pieces. The lightest fodder drops from the snapping-rolls directly onto the rear lower portions of the shredding and cutting rolls, and is therefore cut into but few lengths. The heavier the fodder and the stiffer the stalks thereof the farther it is fed upwardly on the inclined shredding and cutting rolls by the su apping-rolls and the throat-feed, and hence the same is caused to be cut into a number of short pieces and its value as feed considerably enhanced. The husks are delivered from between the husking-r'olls 22 and fall therefrom. The ears slide downwardly on the husking-rolls and fall from the lower ends thereof. The cut and shredded fodder drops from between the cutting and shredding rolls, as will be understood. An inclined dischargetrough 35 is shown in Fig. 1 of the drawings to catch the cut and shredded fodder and discharge the same by gravity from the machine.

In Fig. 5 of the drawings we show a modification in the construction of the disks of our snapping and shredding rolls in which the disks are provided midway between their sides and between the bases of their teeth 4 with smaller teeth et, which are triangular in cross-section and which increase the effi ciency of the disks in grasping the fodder and drawing the same between the rolls.

While We have shown the snapping-rolls in Figs. 1 and 2 of the drawings as disposed with the cutting and shredding rolls are shown disposed in three positions with reference to the snapping 1 rolls. Other variations may be made in the relative dispositions of the shredding and snapping rolls within the scope of our invention and the appended claims.

ing the fodder prior to feeding the same to the shredding-rolls. By thus adapting the snapping-rolls to cut the bands of twine by which the corn is bound the fodder is fed in a loose condition from the snapping-rolls to the shredding-rolls and is adapted to readily pass between the shredding-rolls and to be cut into short lengths thereby. The bindingtwineafter having been cut by the snappingrolls drops upon the shredding-rolls, together with the fodder, and is also cut into short lengths In practice the snapping-rolls of our improved machine rotate at a comparatively low rate of speed, and the twineis carried between them, together with the fodder. Should the twine become caught and partly wrapped upon the snapping-rolls, the free end thereof would be caught by the shredding-rolls, and hence twine will be drawn from the snapping rolls by the shredding-rolls. The continuous rotation of the snapping-rolls and shreddingrolls and the peculiar construction thereof insures the cutting of the twine-bands into short lengths and the feeding of the fodder.
